A labeling system, comprising at least one label, wherein the at least one label is configured to receive printing thereon, and wherein the at least one label further comprises a release coating layer; a paper layer; a primer layer deposited on the paper layer; and an adhesive layer deposited over the primer layer, wherein a plurality of score lines have been cut into the at least one label at predetermined locations, to predetermined depths, and in predetermined patterns.

An air-permeable adhesive sheet has air permeability in a thickness direction thereof and including an adhesive agent layer having first through holes extending in the thickness direction, wherein at least one surface of the adhesive agent layer forms an adhesive surface, the through holes have an average opening diameter of 1.0 to 50 m and an average interval of 5 to 400 m, and a variation in air permeability in the thickness direction is 22% or less as represented by a coefficient of variation of an air permeability measured according to Method B for air permeability measurement (Gurley method) specified in JIS L 1096: 2010, with an effective measurement area as a predetermined value selected from 0.5 to 2.0 mm.sup.2. The air-permeable adhesive sheet is a sheet capable of obtaining good characteristics such as air permeability even when being made into a sheet having a small area.

Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

There is a method of manufacturing a multilayer wiring board including: alternately stacking wiring layers and insulating layers; stacking a reinforcing sheet on one surface of the resulting multilayer laminate with a soluble adhesive layer therebetween, wherein an unoccupied region without the soluble adhesive layer is provided within a facing area where the reinforcing sheet faces the multilayer laminate; allowing a liquid capable of dissolving the soluble adhesive layer to infiltrate the unoccupied region to dissolve or soften the soluble adhesive layer; and releasing the reinforcing sheet from the multilayer laminate at the soluble adhesive layer. This method enables the multilayer wiring layer to be reinforced to generate no large local warpage, thereby improving the reliable connection and the surface flatness (coplanarity) of the multilayer wiring layer. The used reinforcing sheet can be released in a significantly short time, while minimizing the stress applied to the multilayer laminate.

Bridge tape with directed foam expansion comprised of thermally foamable composition, useful for applying coating material through holes in the tape to a substrate beneath the tape, after which the holes can be sealed by heating to cause the foamable composition to foam and the foam to seal the holes.

A shock absorber is provided, that includes an adhesive tape portion, a base material stacked on the adhesive tape portion, and a polyurea resin layer stacked on the base material, wherein the polyurea resin layer is divided into a plurality of regions by a cut. A corrosion prevention material and a heat insulating material also include the same adhesive tape portion, the same base material, and the same polyurea resin layer.

A pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer is provided. The pressure-sensitive adhesive layer includes crater portions, each crater portion being concavely formed on an adhesive surface of the pressure-sensitive adhesive layer. A surface of the crater portion has a plurality of through holes.

A protective elastomeric bumper for use with a hand-held electronic device is provided, the bumper comprising: a band, which has a perimeter, the perimeter defining an inner space, the band including an inner surface, an outer surface, and a plurality of apertures extending from the outer surface to the inner surface and continuous with the inner space and an ambient environment, the outer surface including one or more of a central ridge or a pair of outer ridges which extend around the perimeter, the inner surface including a central valley, which extends around the band; and an adhesive, the adhesive located in the central valley.

A device can include a processor; memory accessible by the processor; a battery bay that includes a first surface; a battery package disposed in the battery bay and operatively coupled to the processor, where the battery package includes a second surface; and materials disposed between the first surface and the second surface, where the materials include an adhesive and a thermoplastic.

A tape dispensing system includes packaging tape an application apparatus, and an incision element. The application apparatus is configured to apply the packaging tape to a package. The incision element defines a unique pattern, and is connected to the application apparatus. Movement of the apparatus is effective to punch or incise the unique pattern defined by the incision element completely through the packaging tape and into the package as or after the packaging tape is applied to the package.
